Well, you're brave.
I don't think it'll make the required PF of 120,000. You might get close with .32 H&R Mag ammo, but can the gun handle the pressure?
At any rate, I'm all for pushing the envelope while having fun, and if stages were limited to 7 rounds (and PF weren't an issue), I'd consider it. I don't see myself wanting or needing to improve my Nagant reloading skills, though, especially while the timer's running.
